TOALL WHOM IT MAY CONCERN:

i Be it known that I, CHARLES H. MELLOR, of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Moulding-Macliincs;V and -I do hereby declarethat the following isa full, clear, and'exact description of the construction and operation of the same, reference being had tothe annexed drawings, making a part of this specification, in which.- 'l

Figure'l is a perspective view ci' the whole machine.

Figure 2 is a sectionthrough the dotted line in iig. 1. Similarletters denote like parts in both, iigures. 4

This inventionconsists of a monlding-niachine with-certain mechanica-l devices and arrangements whereby the cutter-head can be' made to revolve either to the right or left, as required.l l l l To enable others skilled in the art to make and use my invention, I will proceed Vto describe its construction.V vand operation.

The frame of this machine is designed to be constructed of iron, with an adjustable wooden top, as below described.

. Letter A,'g. 1, is theframe, cast in pieces, and irmly fastened together by screws, as shown in 'the drawing. Letters B B, iig. 1, is the middle piece, carrying the mandrel N of the cutter-head c. It is also firmly attached, by screws, to the frame A, of `which it makes part.

Letters G C, iig. 1, is a slidingframe, of wood, moving horizontally, and having four inclined faces or planes and metallic screw-plate, by which, in combination with the posts E E, Svc., and wheel F, operating on its 'sere'.vf, passing through the rail G and the said screw-plate, and moving the said france,` the top, D, is elevated or depressed, by the faces of the inclined planes acting against the lower ends of the posts E E, ttc.

Letter D, iig. 1, is the top of the machine, (represented in the drawing as opened, to show the top rail of the middle piece 13,) and is made of wood, with two battens or cross-pieces on its lower side, into which the posts ELE, &c., are framed. l

Letters E E, &c., g. 1, are posts attached to the top D, and sliding4 perpendicular-ly through rabbets or grooves inthe frame A. l l Y Letter F, g. l,.is the wheel by `which, with -its screwf, 5to., as before described, thetop'Dis raised and lowered. I

. Letter G; tig. 1, is a railiotl the frame A, carrying one end oi'` the screwf attached to the wheel F.

Letter H, iigi 1, is a rod by which, in combination with its foot-piece a and slotted lever b, the belt-shifter I is operated.

Letter a, iig; 1, is the foot-piece attached to one end of the rod H.

Letter b, tig. 1, is the slotted lever attachedto the other encloffthc said rod H.

Letter I, iig. 1,118 a shifter for the belts K and L. l

Letter K, fig. 1, is a belt for giving' direct motion to one of the pulleys T T on the journalU.

Letter L, fig. 1, is a crossed belt, for giving a reverse motion to the other of the pulleys T T.

Letter N, iig. 1, is `the mandi-clef the cutter-head, a'nd has two projections, (one at or near eachl end,)

slightly raised above the surface, on, one of which the strap O runs when the mandrel is revolving` to the right,

and on the otherof which it runs when it is revolving to the left.

Letters R R,g. 1, are loose pulleys on the joixrnal U, and carry the beltsK and L when themandrel N is not in motion. v v

Letters T T, iig. 1, are fixed pulleys on thejournal U, and one or othcr'oi' them is operated singly by the strnpsor belts K or L, asv a direct or reverse motion is required. l

Letter M, iig. 1, is the pulley carrying the'strap or belt O, and is fixed on the journal U. Letters P P, figs. 1 and 2, are slides-worliingony projections d in the frame A, and carrying the boxes for sacra 2 the journal .U. They are attached loosely to the frame A by a screw passing through a slot, as shown in the drawing.

Letters e e, gs. 1 and 2, are set-screws, one end passing through the end of the frame A, and the other end into the slide P.

Letter c, iig. 1, is a cutter on the mandrel N, to be substituted by others when necessary. The machine being firmly fixed in place, and the top, D, properly elevated'by means of the wheel F, screw j', slides C C, and sliders E E, lite., the cutter-head c and mandrel N, to which it is attached, are rapidly rotated by the belts L or K and O, and pulleysI T or T and M, operated by suitable power applied to them. Thevpiece of wood to be moulded is then placed upon the top,D, and, guided in contact with the cutter-head, by the hands of the operator, is moulded of the form desired. y

Should the motion of the cutter-head need reversing while' in operation, itzcan be instantly done by the operator placing hisfoot on the vfoot-piece a of the rod H, and moving the belt-shifter I, so as' to changelthc driving-belt running on the pulley T or T from'K to L or Ltol K. When the motion of the mandrel N is thus reversed, the belt O will reverse its position from the projection at one end of the mandrel to thatonthe other end, for which reason a projection at each end of said mandrel is necessary.

Should/the belt O become slack at any time, it can be readily .tightened by means of the thumo-screws e e operating on the slides P l?. Y

The frame A being.of iron,rand veryrm, as constructed and described, conduces, by its solidity, to the smoothness andbeauty of the work done; and the cutter-head being` soquick'ly and easily reversed, saves much time and trouble to the operator.

I am aware of the patent of D. A. Harris, dated February 11, 1868, forV moulding-machine, and do not A claim any of the devices therein; but

The combination of the vertical cutter-bearing mandrel N, having glands for controlling the belt with thc table D, made adjustable vertically by wedges placed on a frame, C, controlled by hand-Wheel F and screwf, all constructed and operated substantially as described.
